Our chimney brush is designed for sweeping chimneys/ducts ( either bricks or stone or steel material； the chimney shapes do not matter, round, rectangular, triangle, etc.) without soft lining. <br/>The nylon bristle of our chimney brush is helical and flexible, so you do not need to trim the bristle short. With the driving force and centrifugal force from the drill chuck, our chimney brush can be used to high efficiently clean the chimneys(note, without soft lining) of inner diameter from 100 mm~700 mm（i.e. 4~28 inches ).
